Definitions
- the invention relates to a pneumatic marker or paint ball gun, to such a paintball gun including a breaking breach feature, to a retrofit kit for converting a conventional paintball gun to embody the improved structure and operation of this invention, and to a methods of making and using such a paint ball gun.
- Paint ball guns were originally developed for marking objects at a distance.
- the guns were employed in such fields as forestry and cattle ranching, in which frangible projectiles (generally known as paint balls) were fired against trees to be harvested, or against cattle to be taken to market, for example.
- frangible projectiles generally known as paint balls
- paint balls When the frangible paint ball hits its target, it breaks open and leaves a brightly colored “paint” mark on the target.
- the paint ball guns themselves are frequently referred to as “markers.”
- more recently paint ball guns are much more widely used in various recreational and game environments, such as simulated war games in which the game players attempt to shoot opposing players with the paint balls, thus marking this opposing player with a particular color of paint from a frangible paint ball. Different colors of paint in the paint balls clearly indicate paint ball hits, and allow players and teams of players to compete against one another.
- Paint ball guns using compressed air or gas for power are well known. Until a few years ago most paint ball guns were pneumatically-powered, but mechanically-operated guns. The recent entry into the market of electro-pneumatically operated paint ball guns provided more consistent and better performing guns for the recreational market. An electro-pneumatic paint ball gun provides improved performance with fewer component malfunctions than the earlier mechanical-pneumatic paint ball guns. However, a common problem with all paint ball guns, and especially those modern recreational paint ball guns which have a high cyclic rate of operation (i.e., a high rate of fire) is the breaking of paint balls in the gun breach and barrel.
- frangible paint balls inconveniently break in the gun itself, and leave the residue of the frangible shell of the paint ball and the paint contained in this shell, within the operating mechanism of the gun.
- a paintball gun so fouled is essentially unusable.
- Another object for this invention is to provide such a retrofit kit allowing a standard paint ball gun with a threadably attached barrel to be modified so that the breach will break open, allowing the barrel to be quickly moved or pivoted aside for removal of fouling.
- a paint ball gun having a main body including a grip frame, a trigger, and the main body also defining a bore for receiving a paint ball.
- An elongate barrel secures to the main body and has a breach end receiving the paintball and a muzzle end from which the paint ball is ejected forcefully.
- a bolt assembly is movable in the main body for opening and closing the breach end of the barrel, and connection structure attaches the barrel to the main body and has a first position aligning and sealingly connecting the barrel with the bore and a second position allowing rapid displacement of the barrel at the breach end from alignment with the bore so that the breach end of the barrel is exposed for cleaning.
- a method of using a paint ball gun includes the steps of providing a paint ball gun having a main body including a grip frame, a trigger, and defining a bore in the main body for receiving a paint ball. Attaching an elongate barrel to the main body with a breach end receiving the paintball and a muzzle end from which the paint ball is ejected forcefully. Providing a bolt assembly movable in the main body for opening and closing the breach end of the barrel, and connecting structure attaching the barrel to the main body and having a first position aligning and sealingly connecting the barrel with the bore and a second position allowing rapid displacement of the barrel at the breach end from alignment with the bore. Whereby in the second position of the barrel the breach end of the barrel is exposed for cleaning.
- a retrofit kit for converting a standard conventional paint ball gun to the advantages of this invention includes a collar member attachable at the location of the paint ball gun barrel by use of a tubular adapter which at an aft end replicates the breach end portion and barrel mounting thread of a paint ball gun barrel.
- the tubular adapter member provides a flange portion which has a shoulder bearing on the collar member when tightened.
- the collar member hingeably carries a hinged portion, and this hinged portion defines a threaded bore for receiving a paint ball gun barrel. In a first position the hinged portion is aligned with the usual position of the paint ball gun barrel, so that the gun is operational normally. In a second position of the hinged portion, the paint ball gun barrel swings aside from its normal position so that the breach is accessible for cleaning.
- An advantage of the present invention is that a paint ball gun according to the invention can be quickly cleaned and placed back into operation after breakage of a paint ball in the breach of the gun. That is, the breach end of the barrel and the breach area of the gun itself are accessible when the barrel is moved to its second location.

- FIGS. 15-17 a fifth embodiment of a paint ball gun according to this invention is illustrated.
- this fifth embodiment like the third and fourth embodiments, allows conversion of a standard or conventional paint ball gun (i.e., one not providing for removal of the barrel other than by time-consuming unthreading of his barrel from the main body of the paint ball gun) to the advantages of this present invention. Because the third and fourth embodiments illustrated the standard or conventional paint ball gun, this fifth embodiment is illustrated in isolation for economy of illustration.
- This fifth embodiment also will be seen to include a kit of parts allowing and effecting conversion of the conventional or standard paint ball gun to enjoy the advantages of this invention because as so retrofitted, the barrel of the standard paint ball gun can be quickly removed for cleaning and just as quickly can be replaced to put the gun back into operation. This quick clearing of the paint ball gun and its return to operation is very important to a competitive paint ball player.
- a quick-release barrel mount 78 for mounting to a conventional or standard paint ball gun includes a first portion 80 which at an aft end part 82 thereof replicates the configuration of the aft end of a standard paint ball gun barrel (recalling FIGS. 11 and 14 , for example.
- This first portion 80 is much the same as part 160 seen in FIG. 13 , and threads into the body of the paint ball gun in place of the barrel.
- the first portion 80 captures thereon and holds in place a generally ring-shaped second part 84 which includes a pair of diametrically-opposed and radially outwardly extending lugs 86 (only one of which is seen in the drawing Figures).
- the second part 84 also defines an elongate boss 92 carrying a spring-loaded detent member 92 a (best seen in FIG. 17 ).
- This detent member 92 a engages in a first relative position of the members 84 and 90 (as is seen in FIG. 15 ) into a shallow detent pocket (not seen in the drawing Figures) defined at the aft face of a detent tab 94 extending radially outwardly on the member 90 .
- a through bore 96 opens, and defines a barrel-receiving thread 96 a.
- a user of the quick-release barrel mount seen in FIGS. 15-17 first attaches the member 84 to the main body of a paint ball gun using the first portion 80 , as was explained above about use of the part 160 seen in FIG. 13 .

- the user of the paint ball gun threadably attaches the member 90 at the aft end of a selected paint ball gun barrel, and attaches the members 84 and 90 together as seen in FIG. 15 by a combination of axial and rotational motion, indicated by the cranked arrow on FIG. 15 .
- This motion engages the arms 88 with the lugs 86 , and results in the detent member 92 a engaging the detent lug 94 .
- the paint ball gun is operational and will shoot paint balls.
- FIGS. 16 and 17 illustrate, in the event the user of the paint ball gun desires to quickly remove the barrel from the paint ball gun (i.e., for cleaning of the barrel and/or breach area of the gun) then a partial turn of the barrel ( FIG. 16 ) of less than 180 degrees, will unlatch the detent 92 a from detent tab 94 . This rotational movement is followed by an axial movement along the axis of the barrel ( FIG. 17 ) which will remove the barrel from the gun for cleaning. Of course, removing the barrel from the gun, also exposes the breach area of the gun for cleaning. Replacement of the barrel onto the paint ball gun is the opposite to removal, and is equally quick. As a result, the paintball gun can be cleaned and quickly be placed back into operation even during a competition or paint ball game.

Abstract
Paint ball guns frequently break paint balls within the gun. When this happens the gun is jammed with paint and residue of broken paint balls, and a user of the gun cannot fire the gun. An improved paint ball gun includes structures and features which allow quick opening of the barrel and breach of the gun for cleaning. After cleaning of the barrel and breach of the gun, the barrel and gun breach are quickly returned to firing position, and a user of the gun loses only a few seconds of game time before being able to resume firing. A kit of retrofit parts, as well as methods of making and operating the improved paint ball gun are also disclosed.
Description
- The invention relates to a pneumatic marker or paint ball gun, to such a paintball gun including a breaking breach feature, to a retrofit kit for converting a conventional paintball gun to embody the improved structure and operation of this invention, and to a methods of making and using such a paint ball gun.
- Paint ball guns were originally developed for marking objects at a distance. The guns were employed in such fields as forestry and cattle ranching, in which frangible projectiles (generally known as paint balls) were fired against trees to be harvested, or against cattle to be taken to market, for example. When the frangible paint ball hits its target, it breaks open and leaves a brightly colored “paint” mark on the target. For this reason, the paint ball guns themselves are frequently referred to as “markers.” But, more recently paint ball guns are much more widely used in various recreational and game environments, such as simulated war games in which the game players attempt to shoot opposing players with the paint balls, thus marking this opposing player with a particular color of paint from a frangible paint ball. Different colors of paint in the paint balls clearly indicate paint ball hits, and allow players and teams of players to compete against one another.
- Paint ball guns using compressed air or gas for power are well known. Until a few years ago most paint ball guns were pneumatically-powered, but mechanically-operated guns. The recent entry into the market of electro-pneumatically operated paint ball guns provided more consistent and better performing guns for the recreational market. An electro-pneumatic paint ball gun provides improved performance with fewer component malfunctions than the earlier mechanical-pneumatic paint ball guns. However, a common problem with all paint ball guns, and especially those modern recreational paint ball guns which have a high cyclic rate of operation (i.e., a high rate of fire) is the breaking of paint balls in the gun breach and barrel. That is, the frangible paint balls inconveniently break in the gun itself, and leave the residue of the frangible shell of the paint ball and the paint contained in this shell, within the operating mechanism of the gun. A paintball gun so fouled is essentially unusable.
- As a result, the user of a fouled paintball gun must discontinue operation of the gun, and in order to clear the gun of paint fouling is required to remove the barrel by unthreading it from the receiver of the gun, then swab it out, as well as cleaning the breach of the gun. Then the barrel is re-threaded onto the receiver of the gun. Because unthreading the barrel from the gun exposes the breach chamber of the gun, cleaning out the barrel removes most of the paintball residue and paint from the gun, and allows removal of the remaining paintball residue and paint from the breach mechanism as well. However, when such a partial disassembly and cleaning of a fouled paintball gun is necessary during a game or competition, the player using the gun incurs a great risk of being hit by opponents, and thus of being put out of the game.
- In view of the deficiencies of the related art, it is an object for this invention to mitigate or eliminate at least one of these deficiencies.
- Specifically, it is an object for this invention to provide a paint ball gun having a breach mechanism allowing the gun to quickly break open at the breach so that the barrel and breach can be cleared of fouling.
- Another object for this invention is to provide such a retrofit kit allowing a standard paint ball gun with a threadably attached barrel to be modified so that the breach will break open, allowing the barrel to be quickly moved or pivoted aside for removal of fouling.
- The present invention addresses the deficiencies of the conventional technology by providing a paint ball gun having a main body including a grip frame, a trigger, and the main body also defining a bore for receiving a paint ball. An elongate barrel secures to the main body and has a breach end receiving the paintball and a muzzle end from which the paint ball is ejected forcefully. A bolt assembly is movable in the main body for opening and closing the breach end of the barrel, and connection structure attaches the barrel to the main body and has a first position aligning and sealingly connecting the barrel with the bore and a second position allowing rapid displacement of the barrel at the breach end from alignment with the bore so that the breach end of the barrel is exposed for cleaning.
- A method of using a paint ball gun according to this invention includes the steps of providing a paint ball gun having a main body including a grip frame, a trigger, and defining a bore in the main body for receiving a paint ball. Attaching an elongate barrel to the main body with a breach end receiving the paintball and a muzzle end from which the paint ball is ejected forcefully. Providing a bolt assembly movable in the main body for opening and closing the breach end of the barrel, and connecting structure attaching the barrel to the main body and having a first position aligning and sealingly connecting the barrel with the bore and a second position allowing rapid displacement of the barrel at the breach end from alignment with the bore. Whereby in the second position of the barrel the breach end of the barrel is exposed for cleaning.
- A retrofit kit for converting a standard conventional paint ball gun to the advantages of this invention includes a collar member attachable at the location of the paint ball gun barrel by use of a tubular adapter which at an aft end replicates the breach end portion and barrel mounting thread of a paint ball gun barrel. At a forward end portion the tubular adapter member provides a flange portion which has a shoulder bearing on the collar member when tightened. The collar member hingeably carries a hinged portion, and this hinged portion defines a threaded bore for receiving a paint ball gun barrel. In a first position the hinged portion is aligned with the usual position of the paint ball gun barrel, so that the gun is operational normally. In a second position of the hinged portion, the paint ball gun barrel swings aside from its normal position so that the breach is accessible for cleaning.
- An advantage of the present invention is that a paint ball gun according to the invention can be quickly cleaned and placed back into operation after breakage of a paint ball in the breach of the gun. That is, the breach end of the barrel and the breach area of the gun itself are accessible when the barrel is moved to its second location.
- Additional objects and advantages of the present invention will become apparent to those ordinarily skilled in the pertinent arts upon reading the following detailed description of a particularly preferred embodiment of the invention, which illustrates the best mode contemplated for practicing the invention, taken in conjunction with the accompanying drawings.

FIGS. 1-3 in conjunction with one another, and first considering especiallyFIG. 1 , apaint ball gun 10 includes amain body 12, with agrip frame 14 pivotally carrying atrigger 16 and defining atrigger guard 18. Abarrel 20 is threadably attached to themain body 12, and defines a breech end opening (indicated by thearrow 22 a-best seen inFIG. 3 ) at which a paint ball may be received into thebarrel 20. At a muzzle end opening 22 b, the paint ball may be discharged from the barrel (indicated by the arrow onFIG. 1 ) by a blast of pressurized gas, as will be well understood by those ordinarily skilled in the pertinent arts. - A gas
inlet regulator body 24 is also attached to and depends from themain body 12, and provides communication via aninlet 24 a (arrowed onFIG. 1 ) with a source of high pressure gas (not shown in the drawing Figures) for powering thepaint ball gun 10. Also attached to themain body 12 via anupper feed tube 26 defining an opening or feedport 28 may be a paint ball hopper and feeding device (not seen in the drawing Figures, but indicated by arrowed numeral 30). Thearrowed numeral 30 also indicates the provision into the feed port or opening 28 of a supply of paint balls which are fed in one at a time in succession. Thefeed port 28 opens into a top one 32 (best seen inFIG. 2 ) of two substantially parallel and vertically spaced bores (i.e., bores 32 and 34) defined by themain body 12, the lower one of which is indicated by an arrowed lead line. Thelower bore 34 at its forward end receives anaccumulator chamber member 36, as is best seen also onFIG. 2 . Thebarrel 20 is threadably received at arear portion 20 c thereof (best seen inFIG. 3 ) into the front ofbore 32, at which themain body 12 defines a barrel-receiving portion 12 a. Thebarrel 20 is able to receive and discharge paint balls, as described above. - A bolt assembly 38 (only a
handle portion 38 a of which is fully seen in the drawing Figures) is reciprocally and sealingly received into the rear portion ofbore 32, and cooperates with thefeed port 28 and with thebarrel 20 at breech opening 22 a to define a breech chamber 40 (best seen inFIG. 2 ) in which a paint ball is sealingly received viafeed port 28 and is held preparatory to this paint ball being forcefully discharged from thegun 10 viabarrel 20, viewingFIG. 1 . In the drawing Figures, the bolt 38 and handleportion 38 a thereof are illustrated in a rearward one of their two operative positions, indicating that the bolt is open. When the bolt handle 38 a and bolt 38 move forward to a second operative position (not seen in the drawing Figures) then the bolt 38 at its forward extent closes thebreach chamber 40 to trap a paint ball therein preparatory to the paint ball being discharged from thebarrel 20. Discharge of the paint ball is indicated onFIG. 1 by the arrow exiting muzzle 22 b. - The
gas inlet regulator 24 provides pressurized gas (i.e., compressed air, or nitrogen, or carbon dioxide, for example) into thelower bore portion 34. A front part of thebore portion 34 communicates with theaccumulator 36 as described above. At the bore portion 34 (i.e., within the body 12), thepaint ball gun 10 includes a discharge valve assembly (not seen in the drawing Figures) which will be well understood to those ordinarily skilled in the pertinent arts, including a poppet valve member arranged to communicating pressurized gas between thebores trigger 16. Thus, when a user of thepaint ball gun 10 pulls thetrigger 16, the pressurized gas is communicated fromaccumulator 36 to thebreach chamber 40 and discharges a paint ball viabarrel 20. - Those ordinarily skilled in the pertinent arts will understand that the
grip frame 14 houses an electronic assembly and valving assembly (also not seen in the drawing Figures). This electronic assembly and valving assembly typically includes a 3-way, normally-closed solenoid valve and a circuit board (disposed within the grip frame 14) and including a microprocessor based control system controlling the operations and timing of thegun 10. - Further considering now the drawing
FIGS. 1-3 , it is seen that in order to allow thebarrel 20 to be moved aside to allow quick cleaning of this barrel and the breach area of thepaint ball gun 10, the front part ofmain body 12 includes a member orportion 42, which is pivotally or hingeably mounted relative to the remainder of the main body via a forwardly extendingpin 44 carried by themain body portion 12, and pivotally received in a protrudingboss 46 of theportion 42. Thus, thisportion 42 is pivotally or hingeably movable between a first position, seen inFIG. 1 , and a second position seen inFIG. 2 . Theportion 42 defines a forward portion ofbore 32, defines barrel thread 12 a, and carries thebarrel 20. In its first position, theportion 42 and thebarrel 20 are aligned withbreach chamber 40, which is defined by a rearward portion ofbore 32 defined within the remainder ofmain body 12. In this first position of theportion 42, a seal is established between therear face 42 a of theportion 42, and theforward face 12 b of themain body 12. Most preferably, a sealing member 48 (best seen inFIG. 2 ) will be disposed at the surfaces defined byfaces FIGS. 1-3 , theseal member 48 is disposed in agroove 48 a circumscribing thebreach chamber 40 at the opening ofbore 32, although the invention is not so limited. Most preferably, thisseal member 48 may include an O-ring or X-ring type of sealing member disposed between these faces and circumscribing thebore 32. - In order to retain the
portion 42 in its first position seen inFIG. 1 , while allowing it to be pivoted at will to the second position seen inFIG. 2 , thisportion 42 defines a latchingbar 50 protruding rearwardly on the side ofportion 42 opposite toboss 46. This latchingbar 50 is arranged to nest into a pocket (indicated by arrow 52) defined along the left side of themain body 12 by the cooperation of alower boss 54, a pair of vertically spacedbosses 56 a and 56 b which cooperatively carry a spring-loadedpivotal latch member 58, and thelatch member 58 itself. As is seen best inFIG. 2 , when thelatch member 58 is moved aside (i.e., outwardly) at itsforward end 58 a by a user of thepaint ball gun 10 pressing inwardly on a rear portion 58 b of this latch member (indicated by the arrow onFIG. 2 ), the latchingbar 50 is able to pivot outwardly and upwardly ofpocket 52, viewingFIG. 2 . As is also seen inFIG. 2 , pivoting of the latchingbar 50 out ofpocket 52 has the effect of pivoting the member or portion 42 (and barrel 20) aboutpin 44 to the second position seen in this drawing Figure. - When the
barrel 20 is pivoted to the position seen inFIG. 2 , the breach opening 22 a of this barrel is exposed and made accessible so that a cleaning swab or brush on a cleaning rod may be run thorough the barrel. Also, the breach area (i.e.,breach chamber 40, for example) of thepaint ball gun 10 is made open and accessible to be cleaned of paint and paint ball debris resulting from breaking of a paint ball in thegun 10. Once the operator of thepaintball gun 10 is finished cleaning thebarrel 20 andbreach area 40, thegun 10 may be put back into operation simply by pivoting the portion ormember 42 back to its position seen inFIG. 1 . Thus, the latchingbar 50 will be received and locked intopocket 52 by the latchingmember 58. - Importantly, as is seen in
FIG. 3 , the member orportion 42 defines abore 42 a which defines the forward portion ofbore 32, defines the barrel-receiving portion 12 a for themain frame 12, and also defines a standard female barrel-receivingthread 52 b allowing a user of the paint ball gun to changebarrels 20 when desired in order to utilize a barrel better fitting a particular lot of paint balls. - Referring now to drawing
FIGS. 4-6 in conjunction with one another a second embodiment of a paint ball gun according to this invention is illustrated. Because the embodiment ofFIGS. 1-3 , and ofFIGS. 4-6 have many features in common with, or features which are analogous in structure or function, these features are referenced inFIGS. 4-6 using the same numeral used above, but increased by one-hundred (100). First consideringFIG. 4 , it is seen that thepaint ball gun 110 includes amain body 112, with agrip frame 114 pivotally carrying atrigger 116 and defining atrigger guard 118. Abarrel 120 is threadably attached to themain body 112, and defines a breech end opening (indicated by thearrow 122 a) at which a paint ball may be received into thebarrel 120. At a muzzle end opening 122 b, the paint ball may be discharged from thebarrel 120. A gasinlet regulator body 124 depends from themain body 112 and communicates via aninlet 124 a (arrowed onFIG. 4 ) with a source of high pressure gas. Thepaint ball gun 110 also defines an upper feed tube 126 with an opening or feedport 128 for receiving a supply of paint balls, indicated byarrowed numeral 130. - The
feed port 128 opens into a top one 132 of two substantially parallel and vertically spacedbores main body 112. Thebarrel 120 is threadably received at a rear portion 120 c into the front ofbore 132, at which themain body 112 defines a barrel-receiving portion 112 a. Thebarrel 120 is able to receive and discharge paint balls, as described above. - A
bolt assembly 138 with a handle portion 138 a is reciprocally and sealingly received into the rear portion ofbore 132, and cooperates with thefeed port 128 and with thebarrel 120 atbreech opening 122 a to define abreech chamber 140 in which a paint ball is sealingly received viafeed port 128. Discharge of the paint ball is indicated onFIG. 4 by the arrow exiting muzzle 122 b. - A front part of the
bore portion 134 communicates with the accumulator 136, and when a user of thepaint ball gun 110 pulls thetrigger 116, the pressurized gas communicated to thebreach chamber 140 and discharges a paint ball viabarrel 120. - Considering now drawing
FIGS. 4-6 , it is seen that in order to allow thebarrel 120 to be moved aside to allow quick cleaning of this barrel and thebreach area 140 of thepaint ball gun 110, the front part ofmain body 112 includes a member orportion 142, which is pivotally or hingeably mounted relative to the remainder of themain body 112 via a vertically extendingpin 144 carried by themain body portion 112, and pivotally received in aboss 146 protruding on the right-hand side of the main body 112 (best seen inFIG. 6 ). It will be understood that the invention is not limited to the pivot axis defined bypin 144 being oriented vertically, and that the embodiment ofFIGS. 4-6 is an example only of a preferred exemplary embodiment of the invention. For example, the pivot axis for themember 142 may be oriented at any desired angle, such that thebarrel 120 is pivoted aside when moved to its second location. Continuing with a consideration of the drawing Figures, it is seen that thisportion 142 is pivotally or hingeably movable between a first position, seen inFIG. 4 , and a second position seen inFIG. 6 . Theportion 142 defines a forward portion ofbore 132, defines barrel-receiving portion 112 a, and carries thebarrel 120. In its first position, theportion 142 and thebarrel 120 are aligned withbreach chamber 140 defined by a forward portion ofbore 132 defined within the remainder ofmain body 112. In this first position of theportion 142, a seal is established between the rear face 142 a of theportion 142, and the forward face 112 b of themain body 112. Most preferably, a sealing member 148 (best seen inFIG. 6 ) will be disposed at the surfaces defined by faces 142 a and 112 b in order to provide a seal between these faces. In the embodiment seen inFIGS. 4-6 , the seal member 148 is disposed in a groove 148 a circumscribing thebreach chamber 140 at the rear opening of the portion ofbore 132 defined within the member orportion 142, as is seen inFIG. 6 . - In order to retain the
portion 142 in its first position seen inFIG. 4 , while allowing it to be pivoted at will to the second position seen inFIG. 6 , thisportion 142 pivotally carries a spring-loaded latching member orpawl 150 protruding rearwardly along the side ofportion 142 opposite toboss 146. This latchingmember 150 is arranged to engage with a latchingboss 152 defined along the left side of the main body 112 (as is best seen inFIG. 6 ) - As is seen best in
FIG. 6 , when thelatch member 150 is moved by an operator of thepaint ball gun 110 upwardly against its spring load this latch member disengages from the latchingboss 152, allowing pivoting of the member orportion 142 aboutpin 144 to the second position seen in drawingFIG. 6 . Again, when thebarrel 120 is pivoted to the position seen inFIG. 6 , the breach opening 120 a of this barrel is exposed and made accessible so that both thebarrel 120 and the breach area (i.e.,breach chamber 140, for example) of thepaint ball gun 110 is made open and accessible to be cleaned of paint and paint ball debris resulting from breaking of a paint ball in thegun 110. As with the first embodiment disclosed and discussed above, once the operator of thepaintball gun 110 is finished cleaning thebarrel 120 andbreach area 140, thegun 110 may be put back into operation simply by pivoting the portion ormember 142 back to its first position, which in this embodiment is seen inFIG. 4 . The latchingmember 150 will re-engage with the latchingboss 152, and will retain thebarrel 120 in its first position. - Also, as is seen in
FIG. 5 , themember 142 defines a bore 142 a (a forward portion of bore 132) which defines a standard thread 152 b allowing a user of thepaint ball gun 110 to changebarrels 120 when desired in order to utilize a barrel better fitting a particular lot of paint balls. - Referring now to drawing
FIGS. 7-9 a third embodiment of a paint ball gun according to this invention is illustrated. As will be seen, this third embodiment includes a standard paint ball gun 210 (i.e., one not providing for removal of the barrel other than by time-consuming unthreading of this barrel from the main body of the paint ball gun). This embodiment also will be seen to include a kit of parts (perhaps best seen inFIG. 9 ), which will be further explained, and allowing and effecting conversion of the standard paint ball gun to enjoy the advantages of this invention. Because the embodiment ofFIGS. 7-9 has many features in common with, or features which are analogous in structure or function, to features depicted and described above, these features are referenced inFIGS. 7-9 using the same numeral used immediately above, but increased by two-hundred (200) over their first use. First consideringFIG. 7 , it is seen that apaint ball gun 210 includes amain body 212, with agrip frame 214 pivotally carrying atrigger 216 and defining atrigger guard 218. Abarrel 220 is threadably attached to the main body 212 (via the retrofit kit—as will be further explained), and defines a breech end opening (indicated by the arrow 222 a—best seen inFIG. 8 ) at which a paint ball may be received into thebarrel 220 for discharge therefrom. At a muzzle end opening 222 b, the paint ball will be discharged from thebarrel 220. - As is seen best in
FIG. 8 , thebarrel 220 is threadably received at a rear portion 220 c thereof into a threadedbore 242 a of amember 242. As is seen inFIG. 7 , in a first position of themember 242, this member and thebarrel 220 align with the front of bore 232, at which themain body 212 of the conventionalpaint ball gun 210 defines a conventional barrel thread (not seen in the drawing Figures). However, in this case, the barrel thread of the paint ball gunmain body 212 does not directly receive a barrel, but receives atubular adapter part 60 of the retrofit kit, which is best seen inFIGS. 8 a and 9. Thistubular adapter part 60 at an aft end portion thereof has anextension 62 and anexternal thread 64, which replicate the aft end of the paintball gun barrel 220, as is seen inFIG. 8 . So, thisadapter part 60 threadably engages into the barrel thread at the front of the conventional paintball gun body 212, as is seen inFIGS. 7 and 8 . Theadapter part 60 at its forward portion includes a flange portion 66 of enlarged diameter, so that it provides a shoulder (indicated byarrowed numeral 68 onFIGS. 8 a and 9). The flange portion 66 defines wrenchingflats 70, and abluff surface 72 upon which abore 74 extending through theadapter part 60 opens. - About the
adapter part 60 is carried acollar member 76 which may be annular or generally of C-shape, as is best seen inFIG. 8 a. On one side thiscollar member 76 defines an outwardly extendingboss 246 which in this embodiment (as is seen inFIGS. 7 , 8, 8 a, and 9), protrudes on the right-hand side of themain body 212. On the opposite side, thecollar member 76 defines a latchingboss 252. At theboss 246, aportion 242 is pivotally or hingeably received, and serves the same function as theportion 142 seen in the embodiment ofFIGS. 4-6 . That is, theportion 242 threadably receives the barrel 220 (refer toFIG. 8 ), and may be pivotally or hingeably movable between a first position, seen inFIG. 7 , and a second position seen inFIG. 9 . Theportion 242 carries a spring-loadedlatching member 250 which engages with the latchingboss 252, as is best seen inFIGS. 7 and 8 . - In order to secure the
collar member 76 non-rotationally in place on the main body of thepaint ball gun 210, the user of the gun removes thebarrel 220, andthreads adapter part 60 into place, trapping thecollar member 76. When theadapter part 60 is nearly fully threaded into the barrel thread at the front of themain body 212, the user selects the rotational position forcollar member 76 which is desired (i.e., selecting the pivot angle orientation for thebarrel 220 as it swings aside to the position seen inFIG. 9 ) and securely tightens theadapter part 60 by application of torque via wrenchingflats 70. When theportion 242 is swung to its first position seen inFIGS. 7 and 8 , theseal member 248 carried in this portion sealingly engages againstbluff surface 72, and thelatch member 250 engages with latchingboss 252. Operation of this retrofitted paint ball gun, and movement of thebarrel 220 to its second position to allow barrel and breach cleaning is the same as for the embodiment described with reference toFIGS. 4-6 . - Referring now to drawing
FIGS. 10-14 a fourth embodiment of a paint ball gun according to this invention is illustrated. Again, this fourth embodiment includes a standard paint ball gun 310 (i.e., one not providing for removal of the barrel other than by time-consuming unthreading of this barrel from the main body of the paint ball gun). In contrast to the retrofit embodiment seen inFIGS. 7-9 (which provided a retrofitted gun similar in function to the embodiment ofFIGS. 4-6 ), however, the embodiment ofFIGS. 10-14 provides a retrofitted paint ball gun with the barrel pivoting aside similarly to the embodiment ofFIGS. 1-3 . This embodiment ofFIGS. 10-14 will also be seen to include a kit of retrofit parts (perhaps best seen inFIGS. 13 and 14 ), which will be further explained. The addition of the retrofit kit of parts to a conventional paint ball gun allows and effects conversion of the standard paint ball gun to enjoy the advantages of this invention. - Because the embodiment of
FIGS. 10-14 has many features in common with, or features which are analogous in structure or function, to features depicted and described above, these features are referenced inFIGS. 10-14 using the same numeral used immediately above, but increased by three-hundred (300) over their first use. First consideringFIG. 10 , it is seen that apaint ball gun 310 includes amain body 312, with agrip frame 314 pivotally carrying atrigger 316 and defining atrigger guard 318. Abarrel 320 is threadably attached to the main body 312 (via the retrofit kit), and defines a breech end opening (indicated by thearrow 322 a-best seen inFIG. 11 ) at which a paint ball may be received into thebarrel 320 for discharge therefrom. At a muzzle end opening 322 b, the paint ball may be discharged from thebarrel 320. - As is seen best in
FIG. 11 , thebarrel 320 is threadably received at a rear portion 320 c thereof into a threadedbore 342 a of a member orportion 342. As is seen inFIGS. 10 and 11 , in a first position of themember 342, this member and thebarrel 320 align with the front of bore 332 (best seen inFIG. 13 ), at which themain body 312 of the conventionalpaint ball gun 310 defines a conventional barrel-receiving portion 312 a (only a part of which is seen inFIG. 13 ). However, in this case, the barrel thread of the paint ball gunmain body 312 does not directly receive a barrel, but receives a tubular adapter part 160, which is best seen inFIG. 13 . This tubular adapter part 160 at an aft end portion thereof has anextension 162 and anexternal thread 164, which replicate the aft end of the paintball gun barrel 320, as is seen inFIG. 11 . So, this adapter part 160 threadably engages into the barrel thread at the front of the conventional paintball gun body 312, as is seen inFIGS. 12 and 13 . The adapter part 160 at its forward portion includes a flange portion 166 of enlarged diameter, so that it provides a shoulder 168. The flange portion 166 defines wrenchingflats 170, and abluff surface 172 upon which abore 174 extending through the adapter part 160 opens. About the adapter part 160 is rotationally carried a generally C-shapedcollar member 176 which on one side outwardly defines aboss 346 which (as is best seen inFIGS. 12 and 13 ), protrudes on the right-hand side of themain body 312. - A forwardly extending
pin 344 is carried by themain body portion 312 viacollar member 176, and this pin is pivotally received in a protrudingboss 346 of the pivotingportion 342. Thus, this pivotingportion 342 is pivotally or hingeably movable between a first position, seen inFIGS. 10 and 11 , and a second position seen inFIGS. 12 and 13 . The pivotingportion 342 defines a forward portion ofbore 332, defines barrel-receiving portion 312 a, and threadably receives the adapter part 160 atportion 162 thereof. In its first position, the pivotingportion 342 and thebarrel 320 are aligned with breach chamber 340, which is defined by a rearward portion ofbore 332 defined within the remainder ofmain body 312. In this first position of theportion 342, a seal is established between therear face 342 a of theportion 342, and theforward face 172 of the adapter member 160. Most preferably, a sealing member of O-ring configuration, for example, will be disposed at the surfaces defined by thefaces - On the opposite side (i.e., along the left-hand side of the paint ball gun 310), the
collar member 176 defines a latchingboss 352. At theboss 346, a protruding spring-loaded detent member 346 a is received, and serves a latching function when the barrel is in its first position seen inFIGS. 10 and 11 . In this embodiment, the user of thepaint ball gun 310 has simply to apply a sufficient pivoting force (indicated onFIG. 12 by the arcuate arrow) so as to overcome the detenting force supplied by the member 346 a. When the user applies a sufficient pivoting torque, thebarrel 320 andmember 342 will pivot aside to the position seen inFIGS. 12 and 13 . After the barrel and breach are cleaned, the user of thegun 310 simply swings the barrel andportion 342 back to the position seen inFIGS. 10 and 11 , at which the detent member 346 a will snap intoboss 352. Operation of this retrofitted paint ball gun is the same as for the embodiment described with reference toFIGS. 1-3 . - Referring now to drawing
FIGS. 15-17 a fifth embodiment of a paint ball gun according to this invention is illustrated. As will be seen, this fifth embodiment, like the third and fourth embodiments, allows conversion of a standard or conventional paint ball gun (i.e., one not providing for removal of the barrel other than by time-consuming unthreading of his barrel from the main body of the paint ball gun) to the advantages of this present invention. Because the third and fourth embodiments illustrated the standard or conventional paint ball gun, this fifth embodiment is illustrated in isolation for economy of illustration. - This fifth embodiment also will be seen to include a kit of parts allowing and effecting conversion of the conventional or standard paint ball gun to enjoy the advantages of this invention because as so retrofitted, the barrel of the standard paint ball gun can be quickly removed for cleaning and just as quickly can be replaced to put the gun back into operation. This quick clearing of the paint ball gun and its return to operation is very important to a competitive paint ball player.
- First considering
FIG. 15 , it is seen that a quick-release barrel mount 78 for mounting to a conventional or standard paint ball gun (not seen inFIGS. 15-17 ) includes a first portion 80 which at anaft end part 82 thereof replicates the configuration of the aft end of a standard paint ball gun barrel (recallingFIGS. 11 and 14 , for example. This first portion 80 is much the same as part 160 seen inFIG. 13 , and threads into the body of the paint ball gun in place of the barrel. The first portion 80 captures thereon and holds in place a generally ring-shapedsecond part 84 which includes a pair of diametrically-opposed and radially outwardly extending lugs 86 (only one of which is seen in the drawing Figures). Theselugs 86 are engaged by a matching pair of hook-shapedarms 88 protruding rearwardly from abarrel mount member 90. As is seen best inFIGS. 15 and 17 , thesecond part 84 also defines anelongate boss 92 carrying a spring-loaded detent member 92 a (best seen inFIG. 17 ). This detent member 92 a engages in a first relative position of themembers 84 and 90 (as is seen inFIG. 15 ) into a shallow detent pocket (not seen in the drawing Figures) defined at the aft face of adetent tab 94 extending radially outwardly on themember 90. At a forward end opening of themember 90, a throughbore 96 opens, and defines a barrel-receivingthread 96 a. - A user of the quick-release barrel mount seen in
FIGS. 15-17 first attaches themember 84 to the main body of a paint ball gun using the first portion 80, as was explained above about use of the part 160 seen inFIG. 13 . Thepart 84 defines a bluff surface against which a seal member (not seen in the drawing Figures) carried onmember 90 sealing engages in the first relative position of these parts. Then the user of the paint ball gun threadably attaches themember 90 at the aft end of a selected paint ball gun barrel, and attaches themembers FIG. 15 by a combination of axial and rotational motion, indicated by the cranked arrow onFIG. 15 . This motion engages thearms 88 with thelugs 86, and results in the detent member 92 a engaging thedetent lug 94. As so mounted, the paint ball gun is operational and will shoot paint balls. - As
FIGS. 16 and 17 illustrate, in the event the user of the paint ball gun desires to quickly remove the barrel from the paint ball gun (i.e., for cleaning of the barrel and/or breach area of the gun) then a partial turn of the barrel (FIG. 16 ) of less than 180 degrees, will unlatch the detent 92 a fromdetent tab 94. This rotational movement is followed by an axial movement along the axis of the barrel (FIG. 17 ) which will remove the barrel from the gun for cleaning. Of course, removing the barrel from the gun, also exposes the breach area of the gun for cleaning. Replacement of the barrel onto the paint ball gun is the opposite to removal, and is equally quick. As a result, the paintball gun can be cleaned and quickly be placed back into operation even during a competition or paint ball game. - Referring now to drawing
FIGS. 18 and 19 , a sixth embodiment of a paint ball gun according to this invention is illustrated. This sixth embodiment also has many features in common with, or features which are analogous in structure or function, to those depicted and described above. These features are referenced inFIGS. 18 and 19 using the same numeral used above, but increased by four-hundred (400) over their first appearance. Considering FIG. 18, it is seen that the paint ball gun 410 includes amain body 412, with agrip frame 414 pivotally carrying atrigger 416 and defining atrigger guard 418. Abarrel 420 may be threadably attached to the main body 412 (as will be further explained). Thisbarrel 420 defines a breech end opening (indicated by the arrow 422 a) at which a paint ball may be received into thebarrel 420 for forceful discharge. The paint ball gun 410 also defines an upper feed tube 426 with an opening or feed port 428 for receiving a supply of paint balls, as will be well understood. - The feed port 428 opens into a top one 432 of two substantially parallel and vertically spaced
bores main body 412. Thebarrel 420 is threadably receivable at a rear portion 420 c into the front ofbore 432, at which themain body 412 defines a barrel-receiving portion 412 a. Thebarrel 420 is able to receive and discharge paint balls, as described above. A bolt assembly 438 with a handle portion 438 a is reciprocally and sealingly received into the rear portion ofbore 432. - Considering now drawing
FIGS. 18 and 19 in greater detail, it is seen that in order to allow thebarrel 420 to be quickly attached to and removed from themain body 412, the body defines a screw thread 412 a which in this embodiment is circumferentially interrupted. That is, the screw thread 412 a defines one or more axially extending “grooves” at which the screw thread 412 a is interrupted. Similarly, viewingFIG. 19 , thebarrel 420 at screw thread portion 420 c is circumferentially interrupted, and defines one or more matching axially extending grooves at which the screw thread 420 c is interrupted. It will appear that the screw thread sections at 420 c onbarrel 420 are receivable axially into the grooves defined by screw thread 412 a of thebody 412. Thus, as is seen inFIG. 18 , a user of the gun 410 may mount thebarrel 420 to thebody 412 by first inserting the portion 420 c axially into the bore part 412 a, with the thread parts of each passing along the grooves of the other, and then rotating the barrel 420 a part turn to lock the barrel in place. This axial-followed-by-rotational movement is represented onFIG. 18 by the cranked arrows adjacent tobarrel 420, indicating the first axial motion, followed by the rotational motion. Thebarrel 420 is removed frommain body 412 by opposite motions. - In view of the above, it will be seen that
main body 412 may employ conventional or standard paint ball gun barrels, which simply thread into place conventionally. Similarly, thebarrel 420 may be employed on a conventional or standard paint ball gun, and will simply thread into place conventionally. However, whenmain body 412 andbarrel 420 are used together, then thebarrel 420 may be quickly installed on and removed from themain body 412 by a combination of axial and rotational motions as described above. As before, when thebarrel 420 is removed form themain body 412, the barrel and breach area of the gun 410 are available for cleaning. - Referring now to drawing
FIGS. 20 and 21 in conjunction with one another a seventh embodiment of a paint ball gun according to this invention is illustrated. Because the embodiment ofFIGS. 20 and 21 have many features in common with, or features which are analogous in structure or function, to features illustrated and described in prior embodiments of the invention, these features are referenced inFIGS. 20 and 21 with the same numeral used above, but increased by another increment of one-hundred (100) over the last prior use. - First considering
FIG. 20 , it is seen that thepaint ball gun 510 includes amain body 512, with agrip frame 514 pivotally carrying atrigger 516 and defining atrigger guard 518. Abarrel 520 is threadably attached to themain body 512, and defines a breech end opening (indicated by thearrow 522 a) at which a paint ball may be received into thebarrel 520. At a muzzle end opening (not seen in the drawing Figures) the paint ball may be discharged from thebarrel 520. A gasinlet regulator body 524 depends from themain body 512. Thepaint ball gun 510 also defines anupper feed tube 526 with an opening or feedport 528 for receiving a supply of paint balls, indicated byarrowed numeral 530. - Considering now drawing
FIGS. 20 and 21 in detail, it is seen that in order to allow thebarrel 520 to be moved from a first or operative position allowing thegun 510 to be fired and to a second or opened position allowing both the bore of thebarrel 520 and the breach area of themain body 512 to be cleaned, themain body 512 includes aportion 542, which at a forward end threadably receives the barrel 520 (as is seen inFIG. 20 ). At its aft end, theportion 542 includes arearwardly extending tang 542 a, which on an underside thereof defines a female dovetail feature (indicated byarrow 542 b onFIG. 21 ). Themain body 512 defines a matching male dovetail feature 512 a (best seen inFIG. 21 ) onto which the female dovetail feature of theportion 542 is axially receivable, as is indicated by the large movement arrow inFIG. 21 . As is indicated inFIGS. 20 and 21 , themain body 512 carries a pair of spring-loaded latching fingers 558 a and 558 b (best seen inFIG. 21 ). These latching fingers each engage a respective one of a pair oflatch protrusions 550 a, 550 b (only one of which is seen fully inFIG. 21 ) in order to retain theportion 542 andbarrel 520 is their operative position, as is seen inFIG. 20 . When the latching fingers 558 a and 558 b are operated by a user of thepaint ball gun 510, and thebarrel 520 andportion 542 may slide forwardly along and off of thedovetail 512 a (i.e., leftwardly viewing the drawing Figures, as is indicated by the double-headed movement arrow inFIG. 21 ). Then the breach end ofbarrel 520 and the breach area of themain body 512 are exposed for cleaning. Restoration of the barrel andportion 542 onto thegun 510 to return the gun to operation is illustrated inFIG. 21 by the right-ward direction of the double-headed motion arrow. - Referring now to drawing
FIGS. 22 and 23 in conjunction with one another yet another embodiment (i.e., an eight embodiment) of a paint ball gun according to this invention is illustrated. Again, because the embodiment ofFIGS. 22 and 23 have many features in common with, or features which are analogous in structure or function to, features illustrated and described in prior embodiments of the invention, these features are referenced inFIGS. 22 and 23 with the same numeral used above, but increased by another increment of one-hundred (100) over the last prior use. - First considering
FIG. 22 , it is seen that thepaint ball gun 610 includes amain body 612. Abarrel 620 is threadably attached to themain body 612, and defines a breech end opening (indicated by the arrow 622 a) at which a paint ball may be received into thebarrel 620. At a muzzle end opening (not seen in the drawing Figures) the paint ball may be discharged from thebarrel 620. Considering drawingFIGS. 22 and 23 in comparison to one another, it is seen that in order to allow thebarrel 620 to be moved from an operative position allowing thegun 610 to be fired and to an opened position allowing both the bore of thebarrel 620 and the breach area of themain body 612 to be cleaned, themain body 612 includes aportion 642, which at a forward end threadably receives the barrel 620 (as is seen inFIG. 22 ). - At its aft end, the
portion 642 includes a pair of rearwardly extendingtangs 642 a, 642 b (only one of which is fully seen inFIG. 23 ). Thesetangs 642 a/b are vertically spaced apart, and cooperatively define a laterally-extending female dove tail groove, indicated onFIG. 23 with the numeral 642 c. Themain body 612 defines a matching vertically spaced apart and laterally-extending male dovetail feature 612 a, 612 b (best seen inFIG. 23 ) onto which the female dovetail feature 642 c of theportion 642 is axially receivable, as is indicated by the double-headed motion arrow seen inFIG. 23 . When theportion 642 is received onto the dovetail feature 612 a, 612 b, as is seen inFIG. 22 , thegun 610 is operational and may be fired. Conversely, when an operator of thegun 610 slides thebarrel 620 andportion 642 laterally to the relative position seen inFIG. 23 , then the bore of thebarrel 620 and the breach area of themain body 612 are exposed for cleaning. - As is best seen in
FIG. 23 , themain body 612 defines adetent recess 646, which will be engaged by a protruding detent member (not seen in the drawing Figures) carried at the aft face ofportion 642 when thebarrel 620,portion 642, and main body are in their relative position seen inFIG. 22 , so that thegun 610 is operational to fire a paint ball. To move theportion 642 andbarrel 620 between the positions seen inFIGS. 22 and 23 , the user of thepaint ball gun 610 simply applies a sufficient lateral force to overcome the detent force provided atrecess 646, and theportion 642 will slide laterally on or off of the dovetail features described above. - While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments but is intended to be limited only by the spirit and scope of the appended claims, giving full cognizance to equivalents, and to various modifications and improvements as is permitted under the law. For example, it is apparent that the embodiment of
FIG. 18 could employ another version of an interrupted thread type of engagement. However, considering the disclosure set out above, it is apparent that this invention provides a paint ball gun in which the breach end of the barrel, and the breach of the gun mechanism, may both be quickly accessed for cleaning with a movement of the barrel through less then 360 degrees. In most of the present embodiments, the barrel and gun breach are accessible with a movement of 90 degrees or less.
